## What is the median of 33, 86, 68, 32, 80, 48, 70?

A. 32
B. 68
C. 80
D. 86
Explanation: To find the median of a set of numbers, you first need to order the numbers in ascending or descending order.

{32, 33, 48, 68, 70, 80, 86}

The median is the middle value when a data set has an odd number of observations.

The middle value of 7 numbers is the 4th one, which is 68.

So, the median of this set is 68.

## In a moderately skewed distribution, the following equation indicates the relationship among mean, median and mode:
